The low temperature (<50°) geothermal field of Acquasanta is located in a carbonate reservoir in the core of an anticline surronded by marls and sandstones acquiclude. The thermal water rises along an extended fracture system related to strike-slip faults. Thermal and geochemical dilutions occur in the upper part of the water-table. The water temperatures recorded in a deep karst system, show a predominant convective heat transfer along the fractures and a conductive thermal flow in the rock matrix. The hydrogeological system can be related to a thermally driven convective circulation, with a regional recharged area located in the Sibillini Mountains, a flow few kilometres depth, and a discharge along the F. Tronto valley.

Abstract
The low temperature (<50°) geothermal field of Acquasanta is located in a carbonate reservoir in the core of an anticline surronded by marls and sandstones acquiclude. The thermal water rises along an extended fracture system related to strike-slip faults. Thermal and geochemical dilutions occur in the upper part of the water-table. The water temperatures recorded in a deep karst system, show a predominant convective heat transfer along the fractures and a conductive thermal flow in the rock matrix. The hydrogeological system can be related to a thermally driven convective circulation, with a regional recharged area located in the Sibillini Mountains, a flow few kilometres depth, and a discharge along the F.
